PENNSYLVANIAN SPORES OF ILLINOIS 



Delwood and Pope Creek Coal 

 Beds 



The Delwood coal bed in the NW. j4 

 NW. i/J sec. 3, T. 10 S., R. 6 E., Saline 

 County, is correlated by plant spores with 

 the Pope Creek coal bed in the SE. 14 

 SW. 14 SE. 14 sec. 11, T. 7 N., R. 1 E., 

 Fulton County, Illinois. This correlation 

 is in agreement with that by Wanless 

 (1939), Weller, Henbest, and Dunbar 

 (1942), Moore, Wanless, Weller et al. 

 (1944), and Cooper (1946). 



Spores are not as abundant as in the 

 Willis and Tarter coal beds. The follow- 

 ing list includes genera and species which 

 are present in both the Delwood and Pope 

 Creek coal beds unless otherwise indicated : 



1. Punctati-sporites fene stratus sp. nov. 



2. P. reticuloides sp. nov. 



3. P. sulcatus Wilson and Kosanke, 1944 



4. Granulati-sporites pallidus sp. nov. 



5. G. 'verrucosus (Wilson and Coe) S. W. 

 and B., 1944 



6. Laevigato-sporites punctatus sp. nov. 



7. L. desmoinensis (Wilson and Coe) S. W. 

 and B., 1944 



8. L. minimus (Wilson and Coe) S. W. and 

 B., 1944 



9. L. minutus (Ibrahim) S. W. and B., 1944 



10. L. ovalis sp. nov. 



11. Denso-sporites sphaerotriangularis sp. 

 nov.* 



12. D. lobatus sp. nov.** 



13. Cirratriradites difformis sp. nov. 



14. C. rotatus sp. nov. 



15. C. maculatus Wilson and Coe, 1940 



16. Endosporites angulatus Wilson and Coe, 

 1940 



17. E. ornatus Wilson and Coe, 1940* 



18. Triquitrites priscus sp. nov. 



19. T. pulvinatus sp. nov. 



20. Calamospora straminca Wilson and Ko- 

 sanke, 1944 



21. Lycospora granulata sp. nov. 



22. L. pseudoannulata sp. nov. 



23. L. micropapillatus (Wilson and Coe) S. 

 W. and B., 1944 



24. Florinites antiquus Schopf, 1944 



25. "Spherites" sp. 



In addition to the above listed genera 

 and species, a fragment of a spore was ob- 

 served in the Pope Creek coal bed which 

 probably is referable to the genus Rais- 

 trickia. 



The dominant spore genus for the Del- 

 wood and Pope Creek coal beds is Laevi- 

 gato-sporites which comprises 45 percent of 

 the total spore content. Lycospora is the 



next in abundance with about 15 percent of 

 the total spore content being divided among 

 three species of the genus. The Pope Creek 

 and Delwood coal beds may be differenti- 

 ated from the Willis and Tarter coal beds 

 by the presence of Punctati-sporites fenes- 

 tratus sp. nov., P. reticuloides sp. nov., in- 

 creased abundance of Laevigato-sporites 

 and Lycospora^ and reduced numbers of 

 Cirratriradites . 



Rock Island (No. 1) Coal Bed 



The Rock Island coal bed from Pryce 

 Mine (NW. ]/ 4 SE. \/ A SW. \/ A sec. 1, T. 

 16 N., R. 1 W.), Rock Island County, 

 Werner Mine (NE. 1/4 NW. 1/4 SE. \/ A 

 sec. 3, T. 16 N., R. 1 E.), Henry County, 

 and Buggos and White Mine (sec. 33, T. 

 14 N., R. 1 E.), Henry County, is corre- 

 lated with a coal bed which crops out in 

 sec. 23, T. 6 N., R. 1 E., Fulton County, 

 Illinois.

 been observed from all of the above loca- 

 tions unless otherwise noted :
